Building formed of cast vertical and horizontal members

ABSTRACT

An overall building system consisting of field-assembled, precast components, reinforcing means embedded within site-poured concrete that forms portions of the wall and floor surfaces of the building, with the reinforcing means serving to structurally unite the precast concrete components with the site-poured concrete and support the same against tension forces, shear forces, and lateral shafting forces. The precast components include vertical load bearing walls each having vertical voids from top to bottom therein, building slabs preferable of half and full thickness adapted to span the bearing walls and receive reinforcing means thereon as well as concrete, precast stairs, an elevator module for each floor of the building, reinforcing means for tension, shear, and lateral shifting prevention purposes, and site-poured concrete first filling the voids of the load bearing wall and then serving as a floor covering for the slabs.

1. A unitized building of the character described, comprising: A. precast concrete components including
 1. vertical load bearing walls arranged in pairS and in parallel relationship with each other to form a building bay having a length dimension and a width dimension, with each said bearing wall having a series of vertical voids extending from top to bottom internally thereof;
 2. parallelly arranged floor truss slabs that are horizontally positioned between inner and outer perimeter slabs of substantially greater thickness in parallel spanning relationship to the width dimension of each said bay;
 3. said floor truss slabs and said perimeter slabs being supported, in laterally abutted relationship, on the facing longitudinal edges of one pair of said bearing walls in noncovering relationship with the voids thereof; B. shear dowels received in said vertical voids of vertically adjacent bearing walls; C. tension steel horizontally spanning said vertical voids and being positioned on the upper faces of said floor truss slabs in adjacent building bays whereby said tension steel will prevent said longitudinally adjacent floor truss slabs from shifting relatively of each other; D. lateral steel positioned over said floor truss slabs beneath the uppermost surface of said perimeter slabs and extending transversely therefrom for co-action with a transversely adjacent floor truss slab; E. site-poured concrete filling said vertical voids and covering said tension steel, the central portion of said shear dowels, said lateral steel, and covering said floor truss slabs to the height of said perimeter slabs whereby the floor portion of each floor of said building is formed.
 2. parallelly arranged floor truss slabs that are horizontally positioned between inner and outer perimeter slabs of substantially greater thickness in parallel spanning relationship to the width dimension of each said bay;
 2. having a thickness approximately twice the thickness of each said floor truss slabs,
 2. The building of claim 1 wherein one said perimeter slab has a utility core structure secured thereto to define a heart module.
 3. The building of claim 1 further characterized by the presence of corridor slabs that span the space between longitudinally adjacent building bays.
